About

I design and build apps and backend systems, and I live in Sunnyvale.

How I got here

In 2013 I was an accounting intern in Jakarta, at a building materials company, PT. Graha Dinamika Indosteel.

I started computer science at De Anza College in 2013. In 2015 I took a break from it and worked as a data analyst intern at Mountain Kejora Ventures in Jakarta. Then I went to UC Irvine for a BS in Computer Science, Systems and Software, from 2015 to 2017. From 2017 to 2019 I was the founding engineer at Personitech in San Diego, and its only engineer. Since January 2020 I’ve been a senior software engineer at TuringSense in Santa Clara, now part-time.

A senior engineer from TuringSense, who has since left the company, saw me helping some college students at church debug their programming homework. The engineer recommended me to the CEO, who interviewed me personally.

A year into TuringSense, I went back to school and kept the job. I took graduate coursework in Computer Software Engineering at San José State for about a year. I didn’t finish a degree there.

I speak English and Bahasa Indonesia.

Other people’s classrooms

At De Anza I tutored with the Math Performance Success program in three ways: sitting in on classes so students could ask a tutor for help mid-problem, running group sessions of five or six students that went back over a concept from class, and holding one-to-one hours that students booked. One student I remember was a 64-year-old woman who had gone back to college to learn. I adjusted to her vocabulary to help her understand logarithms and exponents.

The program publishes its own results: students in it pass at rates 20 to 50% higher than comparable students in traditional sections, depending on the class. That’s the program’s number, earned by a whole staff of instructors, counselors, and tutors. I was one tutor in it.

Later, Casa de Amistad booked a classroom for me one day a week, and I taught computer science fundamentals there to elementary and middle schoolers. I chose JavaScript because it’s simple to learn, wrote my own syllabus, and taught the class for several weeks. Then the class ended because attendance fell off. It was an interest-based class in a program where the math and English classes are a school necessity.

The IoT club I taught at Canyon Crest Academy bore results. Its members, middle and high schoolers, went from no app-building experience to implementing a real application for a client, and presented it to a board. The Personitech page tells that story.

Cooking and church

I cook for my church about once a month, for thirty to forty people, and help cook for two hundred once a year. Cooking has its own page, and so does what else I do there.

Calisthenics

I train three times a week at home in my own gym room, and I log my workouts in AideyHD. I built my progress skill tree here.
